[emerg] open() "/var/run/nginx.pid" failed (13: Permission denied)

[hardware]

I got this error with the last build from dockerhub https://hub.docker.com/r/wonderfall/nginx/ :

docker logs -f nginx

chown: /var/run/nginx.pid: No such file or directory
nginx: [emerg] open() "/var/run/nginx.pid" failed (13: Permission denied)

Any idea ? Maybe related to this issue : #37

EDIT:

I added touch /var/run/nginx.pid before chown command in run.sh and then rebuild image, now it works.

I'm still getting the following alert in '/log/error.log':
[alert] 8#8: unlink() "/var/run/nginx.pid" failed (13: Permission denied)

Based on: http://serverfault.com/questions/487415/nginx-permission-denied-upstream-error-even-after-777, I changed '/var/run/nginx.pid' to '/var/run' in run.sh which seems to fix it for now.

Someone reported me that even after changing '/var/run/nginx.pid' to '/var/run' like you did, the problem persisted. So we just moved the pid file to /tmp, it seems to work.
